A FIBRE REINFORCED CEMENT COLUMN AND METHOD OF FORMING THE SAME

摘要

A fibre reinforced cement (FRC) tubular body having a wall thickness to outer diameter ratio of less than around 0.050, preferably 0.035. A lathe assembly and method for forming an elongate tubular body, such as said FRC tubular body, is also claimed, said lathe assembly including: an elongate base ( 1 ); a pair of chucks ( 4 ) located at opposite longitudinal ends of said base ( 1 ), said chucks ( 4 ) being configured to engage opposite longitudinal ends of the tubular body; two or more lateral supports ( 11, 12, 17 ) connected to said base to support the tubular body at two or more support locations between its ends; drive means ( 8 ) for rotating the body about a longitudinal axis; and a profiling tool ( 9 ) connected to the base and engageable to machine or profile an outer circumferential surface of the tubular body.
